James,

  I am not having the problem, when I backups run, it backs up seven clients at 
the same time. Did you set "Maximum Concurrent Jobs" in the Storage section in 
bacula-sd.conf?

Here is what I have in bacula-sd.conf Storage section
Storage
{
  Name = backupserv-sd
  SDPort = 9103
  WorkingDirectory = "/backups/working"
  Pid Directory = "/var/run"
  Maximum Concurrent Jobs = 50
}

Here is what I have in Director section for bacula-dir.conf

Director
{
  Name = backupserv-dir
  DIRport = 9101
  QueryFile = "/usr/local/etc/query.sql"
  WorkingDirectory = "/backups/working"
  PidDirectory = "/var/run"
  Maximum Concurrent Jobs = 7
  Password = "xxxxxxx"
  Messages = Daemon
  FDConnectTimeout = 5 minutes
}

This is probably an overkill, but I have also set "Maximum Concurrent Jobs" in 
Storage and Client definition for all client in bacula-dir.conf file.

I had read several posts on bacula mailing lists about Maximum Concurrent Jobs 
but could not find a definitive answer so I added the option where ever it was 
accepted.
